Wave and tidal power have great potential in our drive to de-carbonise our energy production. Whilst it isn't always windy or sunny to power wind and solar, the tides are constant, allowing us to harness a reliable source of energy. The British Isles has a huge potential for wave and tidal energy and particularly in Orkney where the tide flows are very powerful and it is often windy with large waves. Orkney is also home to EMEC, the European Marine Energy Centre, the world's only accredited wave and tidal energy testing station.
